TypeError: request.deviceCodeCallback is not a function when using MSAL Node

Question

I'm encountering an issue with the MSAL Node library where I'm getting a TypeError regarding request.deviceCodeCallback not being a function. Here are the details:

1. Relevant Code: I'm using the acquireTokenByDeviceCode method from the MSAL Node library to perform device code flow authentication. Here's the relevant code snippet:

const response = await publicApplication.acquireTokenByDeviceCode(authCodeUrlParameters, (deviceCodeResponse) => {
    console.log(deviceCodeResponse.message); // Here I'm logging the device code message
});

I've tried reviewing the documentation for MSAL Node and ensuring that my configuration is correct. I've also checked that the values for clientId, authority, and clientSecret are accurate. However, I'm still encountering this error.

This issue occurs specifically when using the device code flow authentication with MSAL Node. I'm developing a Node.js application and integrating with Microsoft Azure Active Directory for authentication purposes.

Answer 1

I followed this MS DOC to get an access token from the Device code flow in JavaScript.

Code :

const msal = require('@azure/msal-node');

const msalConfig = {
    auth: {
        clientId: "<client_ID>",
        authority: "https://login.microsoftonline.com/<tenant_ID>",
    }
};

const pca = new msal.PublicClientApplication(msalConfig);

const deviceCodeRequest = {
    deviceCodeCallback: (response) => console.log(response.message),
    scopes: ["user.read"],
    timeout: 60, 
};

pca.acquireTokenByDeviceCode(deviceCodeRequest).then((response) => {
    console.log("Access token:", response.accessToken); 
}).catch((error) => {
    console.log(JSON.stringify(error));
});

I enabled the mobile and desktop flows in my Azure AD app as below.

Output :

It ran successfully as below:
